Abstract
This invention relates to stable oil-in-water emulsions and to products based on such emulsions which contain a modified polymer which is a copolymer of a preponderant amount of an acrylic acid and a smaller amount of a long chain acrylate monomer which modified polymer renders the emulsions stable for over a year at room temperature and which imparts to the emulsions the quick breaking property whereby the emulsions break on coming in contact with an electrolyte or skin, instantaneously coalescing and releasing oil from the emulsions.
